Scenario 1:
I have a Windows box running IAG (the Microsoft Remote Access solution).
Such box is in the 'perimeter' network. This box is supposed to be joined to
the internal domain in order to allow users to reset passwords, etc.

Scenario 2:
Linux based VPN box. Box is also in the perimeter network. Box is not joined
to the domain at all.
This box requires to have a domain user account with 'reset password rigts'
configured. Hard drive of such machine is protected by strong encryption.

From a security stand point, which solution above is stronger?
